OWC 16GB DDR4 2133MHz CL15 1.2V 260pin SODIMM for HP ZBook G3/G4

OWC 16GB DDR4 SODIMM for HP ZBook G3/G4

This 16GB DDR4 2133MHz CL15 module is built for HP ZBook 14u G4, 15 G3, 15u G3, 17 G3 and Studio G3 mobile workstations. It targets professionals who need more memory capacity for multitasking and larger project files in these specific laptops. The non-ECC unbuffered design matches the factory memory configuration exactly.

260-pin SODIMM installation and common issues

The 260-pin SODIMM form factor fits the memory slots in the listed ZBook models without tools in most cases. A frequent problem occurs when the module is not seated fully; the retaining clips must click on both sides. Another issue is mixing this CL15 1.2V stick with existing memory of different latency or voltage, which can prevent the system from booting.

DDR4 2133MHz PC4-17000 practical limits

The DDR4 2133MHz PC4-17000 interface caps transfer rates at the JEDEC standard specification for this speed grade. Latency is fixed at CL15 and voltage at 1.2V, so there is no headroom for manual overclocking or tighter timings. Total system capacity remains limited by the number of slots and the maximum memory supported by each specific ZBook model.
